An electronic transition from 1s orbital of an atom causes

A

Absorption of energy

B

Release of energy

C

Both release or absorption of energy

D

Unpredictable

Text Solution

Verified by Experts

The correct Answer is:
A

1s is the first and nearest orbital so from 1s, electron can transit to higher orbitals by absorbing energy.
